Answer:

Step-by-step explanation:

-16x^2 + 32x + 2 = 0

Using the quadratic formula:

x = [-32 +/- sqrt((32^2 - 4*-16*2) / (2*-16)

=  1 +/- sqrt (1152)/(-32)

= -0.06, 2.06.

Find the slope that passes through the two points. (9,3) and (6,7)
JulijaS [17]

Answer:

m=4/-3

Step-by-step explanation:

the equation for slope (m) when given two points is (y2-y1)/(x2-x1)

we are given the points (9,3) and (6,7)

we can label the points:

x1=9

y1=3

x2=6

y2=7

now substitute into the equation

m=(7-3)/(6-9)

subtract

m=4/-3

the slope is 4/-3

hope this helps!

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the l
Ymorist [56]

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

We have to determine

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?

<h3>What formula is used to calculate the monthly payment?</h3>

The value of the monthly payment is given by;

\rm P=PV\times \dfrac{i}{1-(1+i)^{-n}}

Where,

  • PV is the present value or the amount of the loan.
  • i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
  • n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Therefore,

The value should be used for n, the number of periods over which the loan is repaid;

n = 6 years × 12 months/year = 60 months = 60 periods.

Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

A SQUARE with side = 14<br>find the diagonal.​
Vinvika [58]

Answer:

14√2

Step-by-step explanation:

A square with a diagonal automatically makes a 45 45 90 triangle (angles) meaning that the two legs are x and the hypotenuse (diagonal) is x√2

If 14 = x then the diagonal is 14√2

You could also solve with the pythagorean theorem

a^2 + b^2 = c^2    so in this case

14^2 + 14^2 = c^2

196 + 196 = c^2

392 = c^2            

√392 = √c^2     the 392 is divisable by 196 so you can divide that out as 14

14√2 = c
